Don't bump into me! Maybe we should all attend the same event and do a 360 shoot. I've not tried yet, but I've heard auto is actually pretty good. I'd imagine a lower iso than one would expect, so as to just catch the fireworks. I've even spotted one or two people using polarised and ND filters. I'm not buying it, but aparently it can help with blown out images for the big finales. And I hear it's good to get above them (higher than her majesty's government might recommend). Check out DSLR and standard video settings. Pretty sure the same tips will apply across the board
